Description

Technical Field

[0001] The utility model relates to the technical field of crusher round rollers, in particular to a wear-resistant round roller for a crusher. Background Art

[0002] A crusher is a device that uses at least two sets of circular rollers to rotate relative to each other and engage with each other, thereby tearing and crushing the material. When in use, the outer surface of the rotating roller is usually assembled with a toothed roller using bolts. In order to facilitate installation, the toothed roller is usually divided into multiple groups, which are spliced ​​end to end to form a circular ring wrapped around the outer surface of the rotating roller.

[0003] Traditional crusher rollers are mostly made using a casting process, with the external roller tip formed integrally with the entire casting. The advantages of this process are high integrity and low manufacturing difficulty. However, during use, it will be found that if the overall material strength used to cast the roller is insufficient (currently mostly 200HB), the roller tip will be easily damaged during use. Damage to part of the roller tip will cause the entire roller to be scrapped, resulting in a short overall service life and high replacement cost. If the overall material is cast with high strength, this will place a greater burden on the casting process and material costs. In order to solve the above problems, a wear-resistant roller for a crusher is provided. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a wear-resistant round roller for a crusher, which solves the problem that if the overall material strength used to cast the round roller is insufficient, the roller tip will be easily damaged during use. The damage to part of the roller tip will cause the entire round roller to be scrapped, the overall service life is short, and the replacement cost is high. If the overall material is cast with high strength, this will impose a greater burden on the casting process and material costs.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions: a wear-resistant round roller for a crusher, comprising a plurality of groups of round roller splicing blocks, wherein the plurality of groups of round roller splicing blocks are connected end to end and spliced ​​into a circle;

[0010] Preferably, both ends of the inner wall of the arc-shaped main body are integrally formed with arc-shaped retaining bars, and the arc-shaped retaining bars are used for vertical positioning of the arc-shaped main body during installation.

[0011] Preferably, an arc-shaped notch is formed between the outer side of the arc-shaped retaining strip and the arc-shaped main body, and an inner concave positioning portion is formed on the opposite side of the two groups of arc-shaped retaining strips.

[0012] Preferably, a fixing hole is provided on the outer surface of the arc-shaped main body, and the fixing hole passes through the arc-shaped blocking bar.

When the main body is manufactured, an L-shaped assembly groove is provided on one side of the rolling protrusion, and then the carbon-silicon-titanium alloy wear-resistant block is welded to the inside of the L-shaped assembly groove using a silver welding process.

[0027] The embodiment of the present application provides a wear-resistant round roller for a crusher, which solves the problem that if the overall material strength used for casting the round roller is insufficient, the roller tip will be easily damaged during use. Damage to part of the roller tip will cause the entire round roller to be scrapped, resulting in a short overall service life and high replacement cost. If the overall material is cast with high strength, this will impose a greater burden on the casting process and material costs.

[0031] The circular roller splicing block 1 comprises an arc-shaped main body 11 and a wear-resistant roller tip 16 arranged on the outer surface of the arc-shaped main body 11;

[0032] The wear-resistant roller tip 16 includes:

[0033] A rolled protrusion 161 is integrally formed on the outer wall of the arc-shaped body 11;

[0034] The carbon-silicon-titanium alloy wear-resistant block 164 is fixedly welded to one side of the rolled protrusion 161 .

[0035] Arc-shaped guard bars 12 are integrally formed at both ends of the inner wall of the arc-shaped main body 11. The arc-shaped guard bars 12 are used for vertical positioning of the arc-shaped main body 11 during installation. An arc-shaped groove 13 is formed between the outer side of the arc-shaped guard bar 12 and the arc-shaped main body 11. An inner concave positioning portion 14 is formed on the opposite side of the two groups of arc-shaped guard bars 12, so that the round roller splicing block 1 cannot move along the axial direction after installation.

[0036] A fixing hole 17 is formed on the outer surface of the arc-shaped main body 11 . The fixing hole 17 passes through the arc-shaped retaining bar 12 and is used for fixing the round roller splicing block 1 on the rotating roller with a bolt or a pin.

[0037] A positioning hole 15 is defined in the arc-shaped notch 13 . The positioning hole 15 passes through the outer wall of the arc-shaped body 11 , so that the arc-shaped body 11 can be quickly positioned during installation.

[0038] The rolled protrusions 161 on the outer surface of each group of arc-shaped bodies 11 are distributed in a 6x6 equidistant pattern.

[0039] An inclined surface 163 is provided on one side of the rolling protrusion 161 , and a vertical surface 165 is provided on the other side of the rolling protrusion 161 , so that the rolling protrusion 161 can have different shearing and crushing effects when rotating in forward and reverse directions.

[0040] An L-shaped assembly groove 162 is provided between the end face of the rolled protrusion 161 and the vertical surface 165. The carbon-silicon-titanium alloy wear-resistant block 164 is fixedly welded in the L-shaped assembly groove 162 by silver welding. The L-shaped assembly groove 162 can be reserved during the main body casting process, or it can be formed by cutting and modifying the traditional round roller.

[0041] The end face of the carbon-silicon-titanium alloy wear-resistant block 164 is flush with the end face of the rolled protrusion 161, and the outer side surface of the carbon-silicon-titanium alloy wear-resistant block 164 is flush with the vertical surface 165, so that the carbon-silicon-titanium alloy wear-resistant block 164 can fit the overall inclination angle of the rolled protrusion 161, thereby improving the service life of the carbon-silicon-titanium alloy wear-resistant block 164.

[0042] A wear-resistant roller tip 16 is provided on the outer surface of the integrally cast round roller splicing block 1, and the entire wear-resistant roller tip 16 includes a rolling protrusion 161 and a carbon-silicon-titanium alloy wear-resistant block 164 welded on the rolling protrusion 161. When the main body is manufactured, an L-shaped assembly groove 162 is provided on one side of the rolling protrusion 161, and then the carbon-silicon-titanium alloy wear-resistant block 164 is welded to the inside of the L-shaped assembly groove 162 using a silver welding process. In this way, the casting cost and process difficulty of the round roller splicing block 1 are the same as those of the traditional round roller. Then, the additionally welded carbon-silicon-titanium alloy wear-resistant block 164 is used to make the carbon-silicon-titanium alloy wear-resistant block 164 contact with the material during the rolling process, and the contact part is stronger and more durable. At the same time, when part of the carbon-silicon-titanium alloy wear-resistant block 164 is damaged, it can be cut a second time and then re-welded, thereby reducing the overall replacement and maintenance cost.
